Claims. (Cl. 118-125) This invention relates generally to apparatus for coating filamentary material in a continuous process and more particularly, relates to Ia novel construction for a tool for installing and operatingv an enameling die structure used in such apparatus.

This invention is a continuation-in-part application of my co-pending appliaction, Serial No. 736,215 filed May 19, 1958, for the invention entitled Wire Enameling Die.

Described and claimed in said co-pending app-lication is a novel die structure which canlbe used -for enameling of electrical magnet wire, for instance. Said die struc ture is comprised generally of a pair of cooperating die parts assembled for selective movement kone relative to the other for opening and closing the same. The' described and illustrated die structure includes a pair of telescopically engaged die parts which can be translated rectilinearly and axially one relative the other and then, rotated on the same axis one relative to the other to achieve a first position in which the die is open to permit insertion or withdrawal of the filament. To close the die, the parts then can be moved one Vrelative the other in reverse order with accompanying automatic engagementi of the filament in the coating forming apertureof the die structure. This die structure is especially useful for a continuous coating process wherein the barey filament is unwound from a reel for passage through abath of thel liquid coating composition of substantially viscous character and thence, through the die structure toform a uni-form coating around the filament. Subsequently,v as

in the case of coating electrical magnet wire, the .coatedv filament can be passed through a baking chamber to dry and harden the coating liquid thereon.

The herein invention solves certain problems relating to installation and operation of the die structure of said co-pending application. As explained in said application, the die is comprised of relatively small parts which can be installed for operation either. on a wall of the liquid coating bath or on a structurey separated from the bath. Because of the relatively small size of the die ,parts and the manner in which they are movable one relative'the other to open and close thel die, it is very difficult to handle and operate the structure when covered with ,the liquid coating material. Such anecessity would arise, for instance, VWhere the filament breaks during the coating process and` it is necessary to re-thread the same through the die structure. Other instances, of course, would arise in connection with installation of the die structure in operative position, replacement of a dieL to coat-a different gauge of wire, cleaning of the die and the like. Further, where the die structure is used in coating of electrical Wire, the liquid insulating composition ordinarily contains 'acid ingredients which can irritate the skin and cause considerable discomfort. It should be understood that these problems also arise in connection with such die structures of other construction in View of the necessity Iwhich may arise to handle rthe die. Y

As for installation and replacement of die structures, under actual production conditions, a multiple-die holder assembly usually is employed so that a plurality of filaments can be coated simultaneously. The limitedspace available and the movements required to open and close the die make it difiicult to handle and manipulate the die parts manually with ease and facility. As a result',v

'rificing any `ofthe* advantages of the invention. g y V In the drawings, wherein thesfame characters of.ref

cf' ICC evenwhen covered with the coating compositiomwithout the .attendant disadvantages hereinabove enumerated.

`Another important object of the invention is to provide a ytool of the character described which comprises a se't wrench for use with a die ystructure of said cofpending application, said wrench including independently operable means for engaging each of the movable die parts of said die structure, said means V:being selectively movable one relative the other for moving said die partsto open and close the die structure.

Another object of the invention' is toprovide 'a set wrench of the character described in whichrsaid engaging means may include a fork lformation for engaging one of the die parts and a locking pin'for engaging theV secondof the die parts, saidpr'neans being movable indedefined Aby said rectilinear path of movement, to open and close the die structure. v v Y Y K Another object of the invention is. to provide a set wrench of the character described which includes a handle having said engaging means operably connected thereon for relative movement to open and close the die structurei without necessitating removal of the die fromits mounting in operational position or for the operator` 'to touch the die.

Another object of the invention is to provide aset-Y wrench of lthe character described which enables -the die Y structure of said yco-pendi'ng application to be installedy in operational position and removed therefrom without complete separation of the die partsthereof. v

lA further object ofthe vinvention is to provide a set wrench of the characterdes'cribed which is character-L ized by its ease of operationrequiring use of only one hand to move the die parts; which can be operated rapidly y andy with sureness; which can be readily and easily modified in structure without departing 'from the principles of operation thereof :for use with modified constructions of the die structure of said co'pending application; which utilizes a simple'economical'construction therefor and which is strong and durable.` S

To facilitate a full understanding of the herein invention, the die structure with which same is intended to be used will be described rst. Referring to FIGS. 4 and 6 initially, the reference character designates generally a die structure embodying the principles of the invention of Said co-pending lapplication and which sometimes hereinafter will be referred as an enameling die. The die 20 is comprised of a pair of die parts or Kshells 22 `and 24 which are telescopically assembled. Each of 4die parts is generally cylindrical in configuration and dimensioned to permit the die part 24 to beslidahly and rotatably received on the interior of the die partr 22. Considering the die part 22, which, is the outer one of the pair, same has an annular knurled or scored formation 25 at one end thereof and van axially extending semi-,cylindrical formation 26 at its opposite end.- A continuous. slot 27 (best seen in FIG. 7) in the annular wall of the shell or sleeve 22 extends longitudinally fromthe knurledv end form-ation 25' through the formation 26 :and is aligned with a groove (not shown) in said formation 26l which cooper-Y ates with asimilar groove in the inner part 24 to forrnthe coating forming aperture 2,8 (FIG. l) in the. closed position ofthe die. Theinner part 24 also has an axially extending semi-cylindricalformatie-11,29 at one. end thereof anda longitudinali-y extending slot 3,0 in the Vannular Wall thereof. The die 2 0V differs in construction from the die designated generally in said ca -pending application by reason of' thev elongated neck or extension 32, at its oppositev end which protrudes axially outward'of the die part- 2,2, and has knurled or scored annular formation 33. In, comparing the die structureV 20 vand the die structure 30 of said 'co-pending application, it will be. noted-Y that knurled end 33 of die part 24 isspaced farther from the knurled end ZS than 4the corresponding parts ofl the die structure 30; of said application. The reason for this construction will be explained subsequently herein.

The, die., parts 22 and 24, also are providedwith a recess 34 and seat formation. 3,5v respectiuely on opposite.,` sides thereof which cooperate in the assemb-led'condrtron ofV die to enable the die to` be operably mounted. Digressing to the illustration of FIG. l, the reference char- 4 acter 36 designates generally a multiple-die holder assembly from which extend a plurality of parallel, spaced apart holder pins 37. The precise structure of the holder 36 and pins 37 and the manner in which they can be installed will not be described in great detail herein. The housing 38 may include a mounting bar 3S' (see FIG. 2) on the interior thereof for supporting pins 37 in kproper extended position. Pins 37 are spaced apart a predetermined distance to permit insertion of a die 20 between an yadjacent pair of pins with the pins received in the cooperating recess 34 and seat formation 35 to support the die therebetween. One of the advantages of this manner of mounting the die 20 is to permit same to float or freely move laterally during the passage of the filament therethrough thereby eliminating any undue strain on the filament which could break the same. Fory la more detailed disclosure of this assembly and the manner of achieving such floating mounting for a die structure embodying the invention of said co-pending application, refference may be had to my co-pending application, Serial No. 838,328, tiled September 4, 1959, for the invention entitled Wire Enameling- Die.

As explained in said application Serial No. 736,215, the die parts 22 and- 24 are selectively movable one relative the other to open and close the die. To close the die, the inner shell V2,4 is moved axially inward relative to the outer shell 22 and then rotated to matingly engage the tapered formations 26 and 29 and form the coatingl forming aperture 28 with the filament 39 engaged therethrough.. In they closed condition of the die, the slots 27 and 30 or entrant means as called in said application Serial No. 736,215, are out of registry (see FIG. 7, ,for instance). To open the die 20, the parts 22 and 24 first are moved axially one relative the other to disengage the formations 26 and 29 and then rotated to place the .slots 27 and 30 in registry one with the other so that a lament 39 can be inserted or Withdrawn through said aligned entrant means.

The novel tool for operating the die 20 is designated generally by the reference character 40 in FIG. 1. Same includes a handle 42v which conveniently, may be made from tubular metal stock and provided with external 1ongitudinal ridges for holding of the tool. OneV end: of the handle has a bifurcated extension 44 between the legs of which is rigidly secured the support member 46 by means of a suitable threaded fastener. The member 46 has the die` part engaging means of the tool movably` mounted thereon spaced from the handle 42.

The member 46 comprises a metal plate. having a ilat end segment 47 which is attached to the handle 42. A bushing 4S is secured transversely through a medial portion of segment 427, as best seen in FIG. 4. The bushing 48 has a cylindrical sleeve segment 49 extending outwardly at a right angle tol bottom surface 5.0 of the :segment 47. An actuator pin Slis slidably engaged through the said sleeve and bushing with the ends of the pin 5l protruding outwardly of the bushing and sleeve respectively. Secured for movement with the pin S1 is the engaging means 52 for moving the die part 24 relative tothe die part 22.

Referring to FIG. 5, the engaging means 52 comprises an elongate metal member having a bifur'ca-ted end segment 53. The legs of the bifur'cated end 53 each haveaV perforated ear 54 through which is engaged the tightening bolt 5S for drawing the legs together so that the member 52 can be rigidly secured to the pin 51 for movement therewith. For this purpose also, Vthe sleeve 49 has portions of the wall thereof removed as shown by opening 49 in FIG. 2 and thepin 51 is flattened on opposite sides.V thereof on the. interior of the sleeve to permit accommodation thereof between legs of the segment 53. Y v i At its opposite end,A the member 52 has a fork formation 56 opening outwardly at an angle relative the 1ongitudinal. axis of the handle. It will further bev seen that fork formation 56 is connected to the end segment 53 by a downwardly bent segment 57 so that the fork is offset from the plane of member segment 53 as well. Considering FIG. 4, the member 52 is secured perpendicular to pin 51 and is disposed below and parallel with the support plate 47 with the fork 56 spaced below the plane of member 47 a distance greater than segment 53.

The engaging means for the die `part 22 is movably mounted on the opposite extremity of the support plate 47. The end face 58 of the plate 47 is arcuately shaped and provided with an arcuate groove 59 opening to said end face along the curved length thereof. Spaced inwardly from said end face is an arcuate track 60 opening to the upper surface of the member'47. The groove 59 and track 60 are separated by a vertically arranged arcuate wall 61 which forms the bottom wall of the groove 59. Slidably mounted in the groove 59 is a block 62 having a reduced dimension tongue 63 at one end thereof extending through an arcuate slot 64 in wall 61. To move the block 62, the extension 63 is secured to the knob 65 by the set screw 66. A locking pin 67 extends axially outward of the opposite end of the block 62 for engagement with the knurled formation 25 of the die part 22.

Referring to FIG. 3, it will be seen that the longitudinal axis of the pin 67 intersects the center of curvature Vof the curved track 60. Likewise, the center of curvatureY of the track 60 lies on a line perpendicular to theY longitudinal axis of the actuator pin 51. The fork 56 and pin 67 liein parallel vplanes and are properly spaced apart to permit engagement thereof with the knurled formations of the die parts 22 and 24 as will now be explained.

To operate the set wrench 40, the fork 56 is engaged with the knurled end 33 of the die part 24 and the locking pin 67 is engaged in a socket 69 suitably positioned in the knurled end 25 of the die part 22. For this purpose, the die part 24 has been provided with the elongate neck 32 so as to suiiiciently separate the knurled ends 33 and 25 to permit the set wrench to move the die parts 22 and 24 one relative to the other for opening and closing the die. Referring to FIGS. 2 and 4, the wrench is shown engaging the die with the solid outline illustration of the gripper means 52 representing the condition where the semi-cylindrical formations 26 and 29 are matingly engaged to form the coating-forming aperture (see FIG. 6 for this condition of the die 20). To

separate the formations 26 and 29, the die parts must be moved rectilinearly one relative the other which is achieved by pressing down on the end 70 of the pin 51 to move the means 52 to the broken outline position 71 thereof. This movement is possible because the locking pin 67 is engaged with the end 25 of die 22 and the hook 56 can be moved linearly.

When the formations 26 and 29 are separated one from the other, the die parts 22 and 24 may then be rotated one relative the other by moving the knob y65 to translate the block 62 and locking pin 67 along the arcuate path of movement to which they are confined. Referring to FIG. 7, the solid outline illustration shows position of the knob 65 to close the die 20 so that the entrant means 27 and 30 of the die are out of registry. To align the entrant means, the knob 65 is translated in a counter-clockwise direction to the position represented by the broken outline 72 thereof. Of course, to rotate the die parts, the semi-cylindrical end formations must be axially displaced one relative the other.

With the die structure installed on the holder assembly 36, the operator can open. and close the die using the wrench 40 with only one hand. With vthe handle 42 lying in the palm of the hand, the pin 51 can be moved up and down withthe thumb and index fingers, as desired. The knob 65 can be moved with the thumb, very readily. There is no opportunity for the operator to come in contact with the die 2.0 during operation of vthe Wrench. Further, the wrench 40 can be used vreadily and conveniently to install the die between a pair of pins or remove the die. By locating the slots 27 and 30 so that only a portion of a completerevolution of one die part relative the other is required to, open or close the die, the tool 40 may bernadey relatively small rand requiring only a relatively small movement of the knob 65 to achieve said open and closed position. It will be appreciated that the ylocking pin is-limited to movement along a path coaxial with the axis of the die.

Another embodiment of the set wrench is illustrated in FIGS. 8 through 16 for use with a modified die strueture embodying the general principlesV of the invention of application Serial No. 736,215 and particularly described and claimed in said second mentioned co-pending application, Serial No. 83 8,328, filed September 4, V1959. The tool is designated generally by the reference character 1,00V and the modified die structure with which the tool is intended to be used is designated generally 102.

Referring to FIGS. V13 and 14, the die structure 102 is comprised of an outer die part 104 and an inner die part 106 telescopically engaged to for-rn the die structure. Said die parts also are generally cylindrical in configuration and are providedv with the semi-cylindrical tapered end formations 108' and 110 respectively which cooperate to 'for-rn the coating forming aperture 112 in the closed position of the die. The die-,102- is distinguishable'from the die 20 and the die 30 of said application Serial-No.

736,215, now Patent No. 2,986,116 because, among other things, it is substantially shorter in overall length. For instance, as seen in FIG. 14 illustrating the die 102 in closed position, the inner die part 106 is received entirely within the die part 104 except for a lug 11"4 protruding outwardly of the die part 104'. The knurled end form-ations `foundr in the other dies described is lacking. The outer die part 104V has an enlarged end formation 116 opposite its end formation 108 having a pair of transverse grooves 118 in opposite sides thereof. Also, the mounting means for the die 102 include substantially rectilinear slots 119 in the outer die `part 104 and a rectilinear seat in the cylindrical wall of the inner die part for accommodating the mounting pin 119' of complementary cross-sectional configuration, all as explained in greater detail in said co-pending application, Serial No.

838,328. For purposes of this disclosure, the multipledie holder assembly 120 of FIG. 8 may be considered the equivalent of the assembly 36, keeping in mind the different configuration of the mounting pins thereof. The entrant slots for the die parts 104 and 106 are shown respectively at 115 and 11'7 in FIGS.V 15 and 16.

The tool 100 includes a handle 122l which may be made from tubular metal stock and closed at one end 123 thereof. Secured to the end 123 `is the support member 125 provided with the integral threaded shank 125 for screwing the member 12S into the end 123. The means for engaging and moving the die par-ts 104 and 106 one relative the other are supported on the member 125.

The means for engaging and moving the inner die part 106 includes an actuating pin 126 slidably mounted transversely through a passageway 127 in a medial portion of the member 125 with the endsof the pin protruding from the passageway. The pin 126 has a longitudinal slot 128 in a surface adjacent one end thereof in which is engaged one end of a set screw 129 threaded through member 125 transverse to and intersecting the passageway 127. Sliding movement of the pin 126 is' .be seen that the pin 133 is movable in a direction ,substantially perpendicular to the plane of the supportv mem- 7 ber 125 and parallel to the path of movement to which the actuator pin 126 is limited.

The end face 134' of the support member 125 has a groove 135 formed therein providing a wall 136 parallel to the plane of the member 125. Said Wall 136 has an arcuate guideway 137 therethrough Ain which is slidably mounted the means for engaging the die part 104. Said means includes a fork formation 138 at one end thereof, the opposite end having a knob 139 including a depending tongue slidably secured in the `guideway 137 by bolt 140 and nut 141.

The center of curvature of the arcuate guideway 137 is intersected `by the longitudinal axis of the locking pin and .a line intersecting the longitudinal axis of the actuator pin 126 at a right angle.

The tool 100 is installed by engaging the fork formation 138 in the grooves 118 of the end rformations 116. The locking pin 133 is receivable in a suitable aperture 140 provided in the lug 114. With the semi-cylindrical end formations 108 and 110 axially displaced one relative the other or disengaged as heretofore explained, the die parts 1014 and 106 are rotatable one relative the other by moving the vknob 139 to move the fork 138 along the arcuate path of movement defined by guideway 137. To move the die parts axially one relative the other along a rectilinear path of movement, the ,actuator pin is moved, translating the inner die part 166 relative thel outer die part 104, provided the formations 108 and 110 are properly positioned one relative the other.

Referring to FIG. 15, the relative position of the engaging means in the closed position of the die is shown, with the entrant slots 115 and 117 out of registry. In FIG. 16, the die parts have been rotated one relative the other by means of the knob 139 to place the slots 115 and 117 in registry or open position of the die. Of course, the relative rotation of the die parts to achieve the position thereof in FIG. 16 from that position shown in FIG. 15 is preceded by the rectilinear movement of the die parts one relative .the other -by means of the actuator pin 126.

It is believed that the invention has been described in sufiicient detail to enable the skilled artisan to understand the governing principles thereof. According to the invention, there is provided a tool for operating a wire enameling die constructed of a pair of telescopically engaged die parts which are' movable one relative the other between a first position opening the die and `a Vsecond position closing the die, Vsaid movement including a rectilinear component of movement and an angular component of movement in succession for opening the die land the same' components of movement, albeit in reverse order, for closing the die, said tool including, -a handle, Support means at one end of the handle and engaging means movably mounted on said support means for independently en-gaging and moving said die parts relative one `another to achieve said open and closed positions of the die.
